BEARING FOR SPINDLES OF SPINNING .AND TWISTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 255,644, dated March 28, 1882.

Application filed May 9, 1881.

To all whom 'it may concern:

Be it known that I, THOMAS MAYOR, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Bearings for Spindles ofSpinning and Twisting Machines; and I hereby declare thatthe following is a full, clear, and exact description ot' the same, reference being bad to the accompanying drawings, forming part of this specification.

This invention has reference to an improvement on Letters Patent No. 215,142, granted to Thomas Mayor, assignor to Joseph Mayor, May 6, 1879.

The object of the invention is to limit the oscillation of the bolster-tube supported on the ball-and-socket bearing; and it consists in the application of wire springs to this bolster, as

will be more fully set forth hereinafter.

Figure 1 is a view of a bolster provided with a ball near the center of its length, to which wire springs are secured by placing the bent end of the wire in a groove made into the ball and resting the wire springs in slots at each end. Fig. 1 is a cross-section on line w .70 of Fig. 1. Fig. 2 is a view ofa bolster provided with a ball near the center of its length, to which wire springs are secured by entering the bent ends ofthe springs into holes made in the ball and resting the wire springs in slots at each end. Fig. 2 is a cross-section on line 3 y of Fig. 2. Fig. 3 is a view of the spindle; and Fig.4 is a sectional view ofthe same, showing the location of the wire springs.

In the drawings, A is the spindle. Bis the sleeve, secured to the spindle and provided with (No model.)

the whirl B; and G is the bolster-case, in which the bolster D is secured by a ball and socket, so as to yield to the motion of the spindle.- The bolster 1) is provided with the balld, which rests in a curved seat in the bolster-case.

e e are bent wire springs interposed between the bolster and the bolster-case, so as to form a yielding resistance to the oscillation of the bolster on the ball-and-socket support. These wire springs can be cheaply made, are easily secured, and as they extend from the ball to the end of the bolster, or about half the length of the bolster, they are stiffer and form a better support for the bolster than springs as heretofore made, extending from end to end of the bolster. By the use of these springs e c, with the bolster D, supported near the middle of its length by the ball d, wabbling or vibratory movement of the spindle is almost entirely avoided, and while the spindle and bolster are freeto adjust themselves to the axial center of the l'oadpthe springs counteract this motion and limit the oscillation of the-bolster.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the spindle A, the sleeve-whirl B, and bolster-caseG, ot' the bol ster D, provided with the ball 0?, and the wire springs 06, secured to the ball d and resting in notches in the bolster end, constructed to limit the oscillation of the bolster, as and for the purpose set forth.
